  • Title: Image interpolation for division of focal plane polarimeters with intensity correlation.
    Author: Zhang J, Luo H, Hui B, Chang Z.
    Journal: Opt Express; 2016 Sep 05; 24(18):20799-807. PubMed ID: 27607683.
    Abstract:
    Division of focal plane (DoFP) polarimeters operate by integrating micro-polarizer elements with a focal plane. These polarization imaging sensors reduce spatial resolution output and each pixel has a varying instantaneous field of view (IFoV). These drawbacks can be mitigated by applying proper interpolation methods. In this paper, we present a new interpolation method for DoFP polarimeters by using intensity correlation. We employ the correlation of intensity measurements in different orientations to detect edges and then implement interpolation along edges. The performance of the proposed method is compared with several previous methods by using root mean square error (RMSE) comparison and visual comparison. Experimental results showed that our proposed method can achieve better visual effects and a lower RMSE than other methods.
